Palmprint identification is a new identification method of physiological biometrics by using palmprint image.As for the pre-processing,six different methods are proposed.The experimental results show useful information by comparison.This paper proposed to use elliptical Gabor filter with least redundancy to convolute with palmprint,sub-bands with 4 scales and 6 directions are obtained,calculate the average and deviation of every sub-band,48D texture feature is extracted,and normalize the 48D feature in the ...
